What Your Dog's Poop Can Tell You About Their Health

Most pet owners don't look forward to poop patrol, but your dog's stool can provide valuable clues about their overall health. By paying attention to changes in your dog's stool, you may catch digestive problems, parasites, or other illnesses early on and often before your dog shows obvious signs of feeling sick.

At East Hills Veterinary Clinic and Red Bank Veterinary Hospital, our team is committed to helping pets live longer, healthier lives. As an AAHA-Accredited veterinary hospital, we follow the highest standards in veterinary medicine, including recommendations for preventive care, parasite screening, and digestive health.

The Scoop on Dog Poop

Every dog poops but not every dog's stool looks the same. Healthy stool is one of the easiest ways to monitor your dog's digestive system and overall well-being.

A dog's stool is made up primarily of water, undigested food (including fiber), bacteria, digestive secretions, and waste products. While every dog is a little different, healthy stool should generally be:

  • Chocolate brown
  • Firm but easy to pick up (similar to Play-Doh®)
  • Well-formed and log-shaped
  • Consistent from day to day

Occasional minor changes can happen after a diet change or eating something unusual, but persistent changes deserve attention.

Decoding Poop Color

Navigating the rainbow of your dog's poop colors can be surprisingly informative. Just like humans, the variation in color in your dog’s stool can provide insights into what’s going on inside your pup.

Let’s decode what different poop colors might indicate about your pooch:

  • Chocolate Brown: This is the gold standard for dog poop and indicates a healthy digestive process. If your dog's poop consistently hits this color, it’s a good sign they’re in good health.
  • Green: Green stool might look alarming, but it often has a simple explanation: excessive grass eating. However, it can also indicate gallbladder issues, so if your dog isn’t a grass grazer, it might be time to schedule an appointment with our team.
  • Black or Very Dark Brown: This can be a warning sign of internal bleeding from higher up in the gastrointestinal tract, possibly the stomach or small intestines.  This condition, known as melena, requires immediate veterinary attention!
  • Yellow: Often seen in dogs with a compromised liver, yellow stools can also suggest issues with the gallbladder or pancreas. This color change is usually accompanied by a more liquid consistency.
  • White Spots: These aren’t about the color of the poop itself, but if you notice white, rice-like specks, your dog could have tapeworms. Schedule a visit with our team as they may need a deworming treatment.
  • Red Streaks or Bright Red Blood: Seeing red streaks in your dog's stool indicates the presence of fresh blood, which can be a sign of bleeding in the lower digestive tract, such as from the colon or rectum. Causes range from mild colitis to parasites or more serious disease. While a small amount may occur with temporary irritation, repeated or significant bleeding should always be evaluated promptly.
  • Gray and Greasy: This type of stool can indicate a problem with the pancreas, specifically an inability to process fats effectively. It could be a sign of a serious condition called exocrine pancreatic insufficiency (EPI).

Any persistent changes in color, especially black, white spots, or red, should prompt a visit to the vet. These changes can be indicators of serious health issues that require immediate attention. 

The Form and More

The consistency of your dog's stool is another important health indicator:

  1. Just Right: A healthy stool should be firm but not too hard, similar in consistency to play dough. It should hold its shape but not be difficult to pass.
  2. Hard Pellets: This can be a sign of dehydration, constipation, inadequate water intake, or insufficient dietary fiber.
  3. Mushy or Formless: If your dog's poop lacks a definite shape, this can point to intestinal problems from a too-rich diet, stress, food intolerance (dietary change), intestinal parasites, or gastrointestinal disease.
  4. Watery: Diarrhea in a dog can range from slight intestinal irritation to severe conditions like viral infections, dietary indiscretion to parasites, bacterial infections, viral disease, or chronic intestinal disorders. Always monitor hydration levels. If diarrhea is severe, bloody, or lasts longer than 24–48 hours, contact your veterinarian.
  5. Size and Amount: These can vary based on how much your dog eats, the type of food they consume, and their size. Generally, dogs on higher fiber diets may produce more voluminous stools.

Normal Oddities

Occasionally, you might notice some peculiarities in your dog's poop that are typically no cause for alarm. Some examples include:

  • Grainy Texture: This can happen when dogs eat too much fiber or indigestible matter like a small amount of sand.
  • Mucous: A small amount of mucus in the stool is normal; it helps to lubricate the colon. If the amount increases significantly but is not accompanied by other symptoms like vomiting or lethargy, it may be due to dietary indiscretion.
  • Grass: Many dogs occasionally eat grass. While the exact reason isn't fully understood, it may be related to normal behavior, taste preferences, boredom, or mild stomach upset. Occasional grass eating isn't usually concerning unless it's excessive or accompanied by illness.
  • Foreign Material: Occasionally finding small amounts of undigested plant material is normal. However, large amounts of foreign material, toys, fabric, or bones should prompt a call to your veterinarian.

Don't Forget About Parasites

One of the most important reasons to monitor your dog's stool is to watch for signs of intestinal parasites. Unfortunately, many parasites including roundworms, hookworms, whipworms, and Giardia cannot be seen with the naked eye.

That's why the Companion Animal Parasite Council (CAPC) and the American Animal Hospital Association (AAHA) recommend routine fecal examinations as part of your dog's preventive healthcare. Even dogs that appear perfectly healthy can carry parasites.

At East Hills Veterinary Clinic and Red Bank Veterinary Hospital, we recommend routine fecal testing based on your dog's age, lifestyle, and risk factors. Early detection helps protect not only your pet but also your family, since some intestinal parasites can affect people!

Spotting Emergencies

Some signs in your dog's stool signify that a trip to the vet is needed pronto:

  1. Persistent Diarrhea: If diarrhea lasts more than a day or two, or if it’s accompanied by vomiting, fever, lethargy, or a decrease in appetite, it’s time to contact your vet. Persistent loose stools can lead to dehydration and may be a sign of something more serious.
  2. Stools with Consistent Blood Presence: Seeing red blood or a tar-like black stool, which indicates digested blood, is cause for concern. This could be a sign of gastrointestinal bleeding or other serious health issues.
  3. Excessive White or Gray Stools: Especially if greasy and foul-smelling, could indicate serious issues in the liver or pancreas.
  4. Excessive Straining or Inability to Defecate: This can be a sign of constipation or, in more severe cases, an obstruction. Both conditions are considered emergencies, especially if your dog appears distressed or in pain.

Keeping Track 

Monitoring your dog's bathroom habits might not be the highlight of your day, but it's a valuable tool in maintaining their health. Here's what you can do:

  • Regular Checks: Make checking your dog’s stool a regular part of your routine. Bringing a fresh stool sample to your dog's annual wellness visit or anytime digestive problems occur.
  • Keep a Diary: If you’re worried about your dog's health, keeping a diary of their stool quality along with their diet can help your vet diagnose any problems more quickly.
  • Diet and Hydration: Provide your dog a balanced diet and ensure they drink adequate water to help maintain normal stool consistency and color.
